Numerical simulation was applied to observe the phenomena inside a crucible in silicon carbide (SiC) sublimation growth. Numerical simulation results show that crystal quality as well as crystal shape strongly depends on the temperature distribution inside the crucible. Numerical simulation also suggested that it is important to reduce the residual stress in the crystal in order to avoid the generation of dislocations. From these results, SiC sublimation growth was controlled actively, and large and high quality SiC single crystal was grown.
